چکیده مقاله:
Circuit breaker (CB) as the critical part of the protection system, is used to isolate power system during faults . Electric power system blackouts and equipment damage may occur if a CB fails to operate due to failure in its interruption chamber. Arc contacts are the most important part of the interruption chamber therefore, condition assessment of these parts are necessary. In this paper, a noninvasive method has been proposed to measure the length of the arc contacts through monitoring of the delay in the drop voltage rise across the CB terminals during opening process. The proposed method has been verified through experiments conducted on a real SF6 CB.
